150,000m 2 . The company’s next goal is to invest in a cold rollingmill.

Macedonian producer of steel welded pipes, IGM Trade, has expanded its range of steel welded pipes. The company’s new pipe line can produce squarepipes up to 250x250x12mm and rectangularpipesup to300x200x12mm, increasing the capacity of the factory to 250,000tperyear.Thecompanyhasalso invested innewslitting lines:onecombo slitting line, and one to accommodate widths of 2,000mm, thickness of 16mm and lengths of 15m. Theownerof the factory,Mr IlijaGechev, said that IGM Trade is the largest green-field investment in South East Europe,with an area of 400,000m 2 and covered space in buildings and halls of thickness being determined by the highest loads occurring in the part. The partmade from a tailored orbital on the othr hand is of varyingwall thickness. In the lower thirdof th seatback,where the heaviest loads occur, thematerial is 1.5 to 2.5mm thick. In the other areas, 1 t 1.5mm is sufficient.

The production programme of IGM Trade also includes round pipes up to 168.3x6mm, tested pipes under pressure of 50 bar up to 88.9x4mm, oval pipes andRP profiles. The company supplies around 10% of its pipes to the domestic market, and exports 90% to the EU and Balkan markets.Production iscertifiedwith ISO 9001 andCE-mark.

Tailored Orbitals ® from ThyssenKrupp Tailored Blanks feature a function- and load-oriented structure precisely matched to the conditions in the part. Unlike other tailored products, they are made from tubular starting material, rather than from flat blanks.

The rotationally symmetrical parts are manufactured on a dedicated laser welding line,onwhichuptofive individual tube segments can be joined together end-on. The individual segments can consist of different materials such as carbon steel and stainless steel, and can have different diameters, different wall thicknesses and different coatings. The result is a starting material that is optimised from theoutset foraparticular application.

IGM Trade’s new linewill allow it to produce an increased range of steelwelded pipes

Steelproducts fromTurkey Hasçelik, amanufacturer and importer of steel products, holds stock of approximately 50,000 tons in six warehouses, to meet urgent requirements. In thecompany’scontinuoushot-rollingmill located inKocaeli,Turkey,hot rolled round, flat, squareandhexagonal steelbars are produced,with a capacity of 200,000 tons per year.Hasçelik also produces cold drawn, peeled and ground steel round bars, aswell as square, hexagonal, and flat bars in two service centres located in Istanbul andKonya. The company’s product range consists of hot-rolled steel bars (round, flat, square and hexagonal), cold drawn bright steel bars (round, flat, square and hexagonal), and peeled or ground bright steel round bars.Main grades are S235JR, St37.2, S355JR,St52.3,C10,C20,C30,C40,Ck45,C60,SAE1010,SAE1020,SAE1030,SAE1040,SAE1045,SAE1050,55CR3 and 60SIMN5. Besides production, Hasçelik imports special steel bars and seamless steel tubes from leading producers. Such products include hot rolled round bars, forged round bars, forged square bars, hot rolled flat bars, seamless steel tubes and ground round bars. Tailored Orbitals for shock absorber reservoir tubes achieve claimed weight reductionsofup to30%.ThyssenKrupp Tailored Blanks has eveloped a new solution for a currentmid-size platform. Unlike the conventional solution, with uniform wall thickness, the Tailored Orbitals solution has a thickness of around2.5mmonly in thehighlystressed lower section of the tube. Further up, wall thicknesses ofwell below 2mm are sufficient. In view of the high cost of the stainless steel used in exhausts, wall thickness reductions have a large impact in the shapeof reducedmaterialcosts.Further savings opportunities are offered by the ability to combine different materials. The use of expensive, highly corrosion– resistant materials can be limited to areas exposed to particular attack from heat and aggressive exhaust gas constituents. TailoredOrbitals can consist of up to five laserwelded segments

Typical areas of use for TailoredOrbitals include car seats, exhaust systems, cockpit support tubes and chassis parts. For example, ThyssenKrupp TailoredBlankshasdevelopeda tailored orbital alternative for a rear seat back reinforcementmade fromaconventional tube. The new solution reduces weight by around a kilogram because the conventional structure is made from a tube of uniform wall thickness, that

Tailored Obitals can be fabricated just like conventional straight-seam welded tubes.Theorbitalsdonothave tobe cut to length first,because this ispart of the manufacturing process, as ismachining of the tubeends.Dimensional tolerances are similar to those of straight-seam weldedtubes.Inaddition,TailoredOrbitals can shorten production processes by combining severalmanufacturing steps. The orbitals are available in lengths of up to 2,500mm, and in diameters that can vary between 30 and 90mmwithin one tube. They can be made in all carbon and stainless steels suitable for laserwelding. ThyssenKruppaG –Germany

CFdesign upfront CFD software integrates compre- hensive fluid-flow and heat-transfer simulation into early phases of design and engineering, when companies can improveproductquality, time-to-market, and ultimately profitability through the product life cycle.

Windows systems,” commented Derrek Cooper, product manager,BlueRidgeNumerics. “It is very important that our customers are able to keep their equipment and operating systems up-to-date and be assured that CFdesign will ‘just work’ on new versions of the Windows platform.” In addition, CFdesign 2010 supports the new Core i7 processor from Intel, providing users with up to 2.5 times info@thyssenkrupp.com www.thyssenkrupp.com operating

Blue Ridge Numerics, Inc, a leader in upfront CFD software, has announced that CFdesign 2010 has been fully tested and is compatiblewithMicrosoft Windows 7. The process ensures that CFdesign 2010 has passed Microsoft- designedtestsforcompatibility,reliability and performance on the Windows 7 platform, using both 32- and 64-bit processors.CFdesign isalsocompatible withWindows XP andWindows Vista.
